It would be nice to be able to zoom in and out with the - and + keys. I don't have a scroll wheel and am unable to scroll, looking at the game so close up is irritating.
The boss project x is VERY annoying, i keep getting pinned in a wall by him then i can't move or i will die and he shoots at me -.- 3/5, I did enjoy the game, nice music great game play but i just can't give it any high when the last boss requires no skill to beat but is still super annoying.
Didn't even think of no scroll wheel! That's a good point/idea.
